Hi I've been using Elementary OS for over a month now and I can't understand why I'm not able to use the single Alt Gr key as a shortcut for moving windows as I had in Linux Mint, for example. I don't think it's anything strange, I'd say Ubuntu is also able to work with that. The problem actually comes when I try to redefine the command with the single key and the system does not let me do it. Any solution? I just need this little feature. The thing is that I'm not sure if this is possible on KDE system basis. Thanks in advance.
